Passing parent's select to child's form

I need to make a select in a parent's form exactly like a select in a child's form onchange.
See the post below...I think I'm close.
Thanks

Hi , you can do this via javascript so I am moving you to that forum.

Ok...
I've put the exact same select dropdown into the child's form
with a style="display:none" which seems to work.
The one in bold is for the child but not working at all.
Maybe I have them backward or there's a better way.
Fix? Thanks

window.onload = function(){
document.sara.sty.onchange = function(){
comments.document.forms[0].sam.className=this.options[this.selectedIndex].value;
comments.document.forms[0].sty.options[document.selectedIndex].value=this.options[this.selectedIndex].value;
}
}

Ha ha! I go to Las Vegas for a week and this still hasn't been answered...Oh well, I turn it around then. Thanks :rolleyes:

try

comments.document.forms[0].sty.options[document.forms[0].sty.selectedIndex]value= ....

What you were trying to do was set the select's value not its selectedIndex...

If both selects have the same option items in the same order,
just set the parent select's selectedIndex to the current select's.

window.onload = function(){
document.sara.sty.onchange = function(){
var parentForm = comments.document.forms[0];
parentForm.sam.className=this.options[this.selectedIndex].value;
parentForm.sty.selectedIndex=this.selectedIndex
}
}

If not, you need to search for it:

window.onload = function(){
document.sara.sty.onchange = function(){
var parentForm = comments.document.forms[0];
parentForm.sam.className=this.options[this.selectedIndex].value;
var parentSelect = parentForm.sty;
var searchString = this.options[this.selectedIndex].value;
for (var i=0;i<parentSelect.options.length;i++){
if (parentSelect.options[i].value==searchString){
parentSelect.selectedIndex=i;
break;
}
}
}
}

Exactly...Thanks. :p
